Additional context
I created a bug-reproduce repo with the latest version, but I can confirm the issue starts at v1.138.0 after #5921 is merged.
After executing the pnpm build (failed), then execute npx vite preview, this error occurs:
error when starting preview server:
Error: Cannot load nitro build info. Make sure to build first.
